and useful Improvements in Tub Drainers or Siphons; and I do hereby declare the following to be full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to drainers for folding bath tubs, wash tubs or other receptacles, and one of the principal objects of the invention is to provide a simple, reliable and efiicient device to be connected to a faucet or water supply connection and to a discharge hose so that the force of water from the faucet will carry the water from the bottom of the tub to a sink or other receptacle to receive the discharge water.

In the use of folding bath tubs, it has been found very inconvenient to discharge the contents of the bath water from the tub after it has been used, and my invention is designed for the purpose of discharging the water from the bath tub or from any receptacle containing water after it has been used and it is desired to empty the receptacle.

The objects and advantages of the invention may be attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of a siphon tub drainer made in accordance with this invention, Fig. 2 is a detail sectional view taken through the nozzles of the draining device, and Fig. 3 is a section taken on the line 3-8 of Fig. 2, looking in a direction indicated by the arrow.

Referring to the drawings, the numeral 1 designates a portable wash tub and 2 is a sink and 3 is a water supply faucet. A hose 1 is connected to the discharge end of the faucet 3 and its opposite end is connected to the inlet end 5 of the siphon plug.

The draining siphon comprises the coupling nipple 5 to Which the smaller hose 4 is connected, and a gradually tapering nozzle 6 having a comparatively contracted discharge end 7. The nozzle 6 is connected integrally to a spider or a plurality of arms 8, said arms being connected integrally to a flaring member or flange 9 formed integrally with the inlet end of the cylindrical body 9,-which is provided witha roughened exterior 10 to Provide a coupling nipple to which the larger hose 11 is connected.

The portable wash tub in connection with which my improved siphon is especially designed to be used, is, as clearly shown in Fig. 1 of the drawing, a well known collapsible type having a body of water-proof canvas. To prevent the walls of the canvas body from being drawn into a position to close the inlet end of the body 9 by and during the operation of the siphon, especially after a considerable amount of water has been drawn from the tub, the flange 9 is provided. The outer edge of the flange 9, since it is located outwardly beyond the axially alined body 9 nozzle 6 and coupling nipple 5, limits the collapsing of the side walls of the canvas body upon the siphon to a point where they cannot close the entrance to the body 9. 1 As the siphon is a one piece structure, it is very simple, it has no parts which have to be assembled before the device may be used and which constantly require adjustment, and it may be manufactured and sold at a comparatively low cost.

In use the draining device, with the hose 4- and the larger hose 11 connected thereto, is dropped into the tub containing the water to be drained OK. The end of the larger hose ll is disposed in a sink or other re ceptacle for the water, and the valve in the faucet 3 is opened to force water through the smaller hose at and through the (1011-: tracted discharge opening 7 in the nozzle 6 to form a suction draft for the water in the tub or receptacle 1, and to carry it up through the apertures 12 between the arms 8 of the spider and into the larger hose 11 where it is discharged into the sink.

From the foregoing it will be obvious that the invention is one of simple construction, being all formed in a single piece, and can be manufactured at low cost, while the device is eflicient for its purpose.

What is claimed is As a new article of manufacture, a one piece siphon for draining collapsible tubs having canvas bodies, comprising a combined coupling nipple and body of cylindrical formation, a flange formed integrally with and flaring outwardly from the inlet end of said body, a tapering nozzle axially alined with said body and'having its discharge end extending into said flange to a ispider connec ting" said nozzle to said flange the siphon body.
